This [[patch]] allows for `\[[sha1]]` substitution in the `diffurl`
for git repositories. This is useful for use with [cgit][] which has
diffurls of the following form:
/project.git/diff/\[[file]]?id=\[[sha1_commit]]
[cgit]: http://hjemli.net/git/cgit/
diff --git a/IkiWiki/Plugin/git.pm b/IkiWiki/Plugin/git.pm
index 5bef928..164210d 100644
--- a/IkiWiki/Plugin/git.pm
